On behalf of the Asia Pacific Signal and Information Processing Association (APSIPA) and the Organizing Committee, we are honored to welcome you to the 18th APSIPA Annual Summit and Conference (APSIPA ASC 2026). This prestigious event will be held at the beautiful Courtyard by Marriott Bangkok Suvarnabhumi Airport in Bangkok, Thailand, from November 9–12, 2026.

APSIPA ASC has come a long way since its inaugural edition in 2009 in Sapporo, Japan. Over the years, the conference has been hosted across the Asia Pacific, the global hub for research and development in signal and information processing, establishing itself as a truly international forum for researchers and practitioners. In parallel, APSIPA as an organization has grown into a vibrant community of researchers, educators, and practitioners dedicated to advancing the field of signal and information processing. It now offers an extensive array of activities for its members, including Distinguished Lecturer programs, seasonal schools, technical committees, and local chapter events, all of which foster collaboration and innovation worldwide.

This year, we are excited to feature a robust program designed to enrich the conference experience. Highlights include insights from our distinguished Keynote Speakers—Prof. Vesa Välimäki, Prof. Baoquan Chen, and Prof. Dacheng Tao—who will share their expertise on topics ranging from audio signal processing to computer graphics and deep model fusion in the AI age. In addition, the conference will host an engaging array of Special Sessions, Grand Challenges, Tutorials, Winter Schools, and Perspective Panels. We are also introducing a new Late Breaking Reports track featuring short paper poster presentations, designed to foster dynamic knowledge exchange, networking, and community building. Collectively, these diverse activities provide unique opportunities to engage with industry leaders and academic experts from across the Asia-Pacific region, inspiring meaningful interactions and advancing the frontiers of our field.

We would like to express our sincere appreciation to everyone who has contributed to making this event possible. In particular, we acknowledge our local organizers, led by Professor Kosin Chamnongthai; the ECTI Association; our technical co-sponsors IEEE and the IEEE Signal Processing Society; and the College of Computing, Prince of Songkla University, as well as our generous industry sponsors, supporting organizations, and exhibitors. Their invaluable contributions have been instrumental in ensuring the success of APSIPA ASC 2026, and we are honored to have them as partners in this endeavor.

Finally, we warmly welcome all participants to APSIPA ASC 2026 and to Bangkok. We encourage you to take full advantage of the rich technical program, engaging discussions, and networking opportunities throughout the conference. We hope you also experience the renowned Thai hospitality during your stay. Thank you for joining us to celebrate innovation, collaboration, and the future of signal and information processing at this summit. We look forward to an inspiring and memorable conference together. See you all at APSIPA ASC 2026!
